Application filed rem-nar 13, 1 920. Serial No. 358,431..

T 0 all to 710m it may concern Be it known that I, MIGUEL ANGEL Qu nooa, citizen of Argentina, and resident of the city of Buenos Aires, Argentina, have invented certain new and useful Improvements in Explosion Engines (for which I have filed an application in Argentina Septeniber 2, 1918 of which the following is a specification. V v v This invention refers to the economization of the naphtha or liquid combustible for explosion engines, and has for its object to provide a suitable,apparatus for regulating the proportions of thenaphtha and the air in the explosive mixture, thus obtaining a notable improvement in the efficiency of such motors, especially those used in. automobiles and motor boats. p

This object is. accomplished by making use. of the excess of naphtha which'is found in nearly all carbureteis, introducing an additional quantity of air in the carbureted gas, thus obtaining the best possible efficiency and at the. same time avoiding the deposit of carbon produced by incomplete gas combustion. This amount of airmust be increased in proportion to the velocity of the car or of the engine, which in accordance with the invention is effected by a system of perforated disks and a wing or butterfly valve, operated by a crank connected to the accelerator rod, as will be more clearly described in the present specification, and specified in the appended. claims.

In the accompanying drawings illustrative of a system of construction embodying my invention, Fig. 1 is a view in side elevation, partially in section of the apparatus; Fig. 2 is a front view of the same, showing the ap paratus mounted 011 the intake pipe of an,

engine; Fig. 3, isa detail of the Wing or butterfly valve; Fig. 4 a view of one of the stationary perforated disks, Fig. 5 of the movable disk, and Fig. 6 is a View of a detail of the device.

In the said drawings 4 and 5 are the two principal parts of the casing of the apparatus which are held together by a screw which serves at the same time for securing the disk 2 in its position. The front part of the casing piece 4; is provided with openings permitting the admission of air which is controlled by means of the perforated disks 2 and 3 and the wingvalve 1.

The disks 2 and 3 are for the purpose of graduating the total amount of air to be mixed with the carbnreted gas, for which v purpose they are provided wit ha number of perforations, in exactly the same relative position in both. disks. These holes may be made to register exactly with each other, or to be partially staggered, for which purpose theyare fastened together-by the screws 16 and 17 which are screwed into the disk 2 and pass through slots in the disk 8, which permlts of a. partial rotary movement of the d1sk 3 upon the disk 2, equal to thediameter of the largest perforations in both disks, obtalnmg this meansa very minute adjustment of the air passages formed by said perforations of the disks 2 and 3. i i i The wing valve or buttcrtiy 1 (see Fig. 3) is for the object of graduating progressively the admission, of air, being operated by a crank 7 which is attached to the accelerator, rod .14. The butterfly 1 in its initial position stops the holes in the'disks 2 and 3, and as it is turned on being acted upon bv the accelerator rod, the holes are gradually uncovered until, at the completion of ninety degrees of said movement, they are left entirely uncovered, so that during such movement the air will have been given a perfectly graduated progressive admission to the explosive mixture. The butterfly l is pressed against the disk 2 by the action of the spring 19, thus forming an hermetical joint.

Figure 2 represents the apparatus placed in position on the intake pipe of a motor, in front elevation, and in this figure there is shown the connection of the crank 7 to the accelerator rod 14 by means of the link 11, one end of which maybe changed from one to another of the holes provided in. said! crank, increasing or diminishing the leverage according to the desired length of travel of the rod 14:.

The other end of the rod 11 is connected to the rod 14 by means of the two clips 13 provided with convenient screws and the universal joint 12. In arranging the valve for operation, the casing is first taken apart, the valve 3 properly adjusted, and the device is then reassembled.

By the foregoing it will be seen that the invention consists of the form of construction of an apparatus for providing an additional admission of air into the carbureted gas used as the explosive mixture in ex plosion engines, by means of perforated disks operated by the accelerator.

It will be also clearly understood that while the relative position and sizes of the said holes as shown in the drawlngs, constitutes an eiiiciently operating example of the invention, the latter is notstrictly limited to the especial arrangement shown, since it will be possible for any one skilled i'nthe' art to vary the position and sizes of said holes, as well as many other details oi con-- struction, without thereby departing from the spirit of the in-\ 'ention as set forth in the following claims.-

Having thus described my i iivention, what I claim and desire to protect'by Letters Patent of the United States of Ai'neriea, is i i lflAn apparatus for regulating the air supply used in explosive mixtures in engines, characterized by the combination 01 a casing having air admission openings, 51 stationary disk mounted in said casing and provided" with air admission openings therethrough, a second disk movable mounted upon the said stationary disk and provit L with air admission openings registering with the similar openings in the stationary disk when the movable disk is in a certain position,-1n*eans to limit the turning movement of said movable disk and to secure the same in adjusted position, a wing or butter fly Valve rotatably mounted on one'of said disks, and aif'rafn'ged to cover and uncover the openings, thereof and an operating said stationary disk and provided with holes registering" with the holes in said stationary disk whenin a certain position and stopping or partially closing said holes in the stationary disk in successive rotary positions of the said movable disk, means to secure said disks together when adjusted, a rotary wing or butterfly valve rotatably mounted on one of the said disks and arranged to cover and uncover the openings thereof, and means to operate said wing or butterfly.
